The ultraviolet disinfection is sterilization through the action of light wave radiation, the disinfection effect is related to the irradiation position and the irradiation intensity, and the ultraviolet disinfection can only be used under the unmanned condition because the ultraviolet is harmful to human bodies.

The hydrogen peroxide disinfection machine atomizes high-concentration hydrogen peroxide solution into fog drops smaller than 10 mu m by an ultrasonic atomization method and a mechanical atomization method, and the fog drops are uniformly released into a target disinfection space. The purification efficiency of similar technique is high, but need release the hydrogen peroxide steam of 200 ~ 1000ppm concentration in target disinfection space, and personnel can't get into during the disinfection, need ventilate after the disinfection and can get into when hydrogen peroxide concentration is less than 1 ppm.

The low-concentration disinfection mode is used for disinfecting and disinfecting the space where people are located, and the concentration of the disinfection and sterilization component must be lower than the safe concentration. This requires the disinfecting liquid to evaporate at a very low evaporation rate and to be distributed uniformly in space and time. The high-disinfection-component-concentration disinfection mode is used for quickly disinfecting and disinfecting an unmanned space, and the effective disinfecting and disinfecting component concentration in the space is required to be very high. This requires that the sterilizing fluid be vaporized at a high rate of vaporization to ensure rapid sterilization and disinfection of the target space.
In some embodiments, when the dual mode evaporation device is operating in the first mode, the first evaporation device is operated and the second evaporation device is kept off.
In some embodiments, when the dual mode evaporation device is operating in the second mode, the second evaporation device is operated and the first evaporation device is kept off.
In some embodiments, in the first mode, an air flow passes through a side wall of the first evaporation device, liquid on an evaporation fabric of the side wall is evaporated, the active ingredient enters the air flow, and the air flow enters the target space through the second evaporation device.
Specifically, in the first mode, the low rate atomization device is activated and the side hollow cavities of the first evaporation device are filled with atomized disinfection droplets. Part of the liquid drops are adsorbed on the side wall evaporation fabric, the air flow flows through the side wall of the low-speed evaporation device, the disinfectant on the side wall evaporation fabric is volatilized, the disinfection components enter the air flow, and the air flow enters the target disinfection space after passing through the high-speed evaporation device.
In some embodiments, in the second mode, the air flow enters from the hollowed-out part of the outer side surface of the cavity with both the inner side surface and the outer side surface hollowed out, and flows out from the hollowed-out part of the inner side surface after passing through the evaporation fabric, and the effective component on the evaporation fabric enters the target space along with the air flow.
Specifically, in the second mode, when the high-rate evaporation device is operated, the high-rate atomization device is started, and atomized disinfection liquid drops enter the bottom hollow cavity body. The air flow flows through the cavity with both the inner side surface and the outer side surface hollowed out. The disinfectant entering the cavity enters the evaporation fabric in the cavity with the inner side surface and the outer side surface both hollowed through the bottom evaporation fabric of the bottom hollowed cavity. The air flow flows through the side surface of the low-speed evaporation device, enters the cavity from the hollow parts of the outer side surfaces of the hollow cavities on the inner side and the outer side, flows out from the hollow parts of the inner side surface after passing through the evaporation fabric, and the disinfection components on the evaporation fabric enter the disinfection space along with the air flow,

The disinfectant is atomized into fine liquid drops through the atomizer, the atomized liquid drops are adsorbed on the evaporation fabric, and the air flow passes through the evaporation fabric to accelerate the evaporation of the disinfectant on the evaporation fabric. The integration of two disinfection modes can be realized through the mutual matching of different atomizer specifications, evaporation area of evaporation fabric, thickness of evaporation fabric and the like. The mode that the atomizer is matched with the evaporation fabric ensures that the effective components for sterilization and disinfection are uniformly distributed in space and time. The material of the evaporation fabric is a material which is resistant to the corrosion of the disinfectant.
The dual-mode evaporation device can generate and uniformly release gaseous disinfection components with specific concentration in a target disinfection space, and not only can kill bacteria and viruses in indoor air, but also can kill the surfaces of indoor objects. Can realize dual mode disinfection of disinfecting, it is more convenient. The unmanned high-disinfection-component-concentration disinfection mode can realize disinfection of indoor air and object surfaces, can realize quick and efficient sterilization, is closed in space when in use and is used for periodical disinfection; the low disinfection component concentration working mode can be used for indoor continuous purification.
